Beit known "that I, Snion KoHN, a subeet of the Emperor of Austria-Hungary? resi g woven and felted fabrics and of Heretofore an attempt was made to utilizeoxenfor the I at the city of Vienna, in the Empire 0 Austria- Hungai'y, have invented certain new and useful Im rovements in Processes of Manufacturing Fi er Material from Animal Tendons or Sinews, of which the following is .a' specification..' i I My invention has relation to a process for manufacturin fiber material from animal sinews orten ons, and in such .connection it relates more particularly tothe treatment. of sinews and tendons to'loosen the fiber thereof so as to render the same workable and adaptable for the manufacture of all kinds of dyeing and tanning when required.

the genital parts of bulls and goduction of fibrous material therefrom.

owever, this object was not accomplished, as these sisting o fieshand skin, and when treated a flour or-powder like mass'was obtained,

which practice has demonstrated was unfit ,for use as a textile material in thearts. n The principal objects of my present invention are, first, to loosen the'structure of. the animal tendons or sinews by subjecting'to a beating durin a simultaneous turning around their longitudinal axis until the sinews or tendons have become hollow in their central portion and thebundles ofthe' fiber mainly constituting the same have -been separated from each other, and, second, to completely separate the bundles of fiber located longitudinally and transversely in the sinewsinto finely-divided threads arranged parallel to each other by a carding or com ing operation.

.The nature and scope of my invention will be morefully understoodfrom the following description, taken in connection with the ac-.

com nying drawings, forming part hereof,"

Fig. 4 is a side elevational view of a tendonorsinew and H1118. the partially-treated upper portion and t e com letely-treated lower thereof; and I 'g. 5 1s a perspective view of a pizzle which has been subjected to the in longitudinal and transverse directions ortion same treatment as the tendon or sinew shown in Figs.- 1 to 4, inclusive. I

From the sinews or tendons are first removed all adhering fiesh and fat and the skin surrounding the same. The sinews or tendons, which during the life ofthe animal are soft and pliable, harden shortly. after death into a sohd and tenaceous material, in which [state the same cannot be utilized. Asshown in Fi 1, the sinew A is mainly composed of ara el and transversely-arranged bundles of iibers a and b, which are separated from each' other by an albumin'ous cement-like substance c. I

In order to separate thebundles of fibersa, and bfrom each other and from the substance 0, the sinews or tendons A are first subjected to a beating, preferably with a hammer-like tool, (not shown) simultaneously with a turning of the same around their longitudinal axis, so that the entire surface and every point of the sinews or tendons A may be subected to such hammer-like blows. The central portion of the tendons or sinews beingcpf 9 5- somewhat less solid texture will more. quic be loosened by the -hamme'r like blows than the outer portions of the same, and hence the sinews or tendons will become hollow in their central portion, as shown in Fig. 2. At this stage of treatment the bundles of fiber a and b, as well as the mass 0, are se arated fromut the longiposition divide the fibers constituting the bundles, the

, sinews A are subjected to a carding and combing operation, by means of which the same are'divided into fine and long fibers or threads d, capable of being used as a new. textile material. The fiber material obtained in the above-described 'manner from sinews. or tendons is now roved in the usual manner and form a fiber which may remain raw and in this state be woven and colored. Furthermore, the webs madeof this fiber may be subjected to a rolling, scraping,

and pressing operation, or the same may be tanned, colore rolled, scraped, and pressed, if desired.

' Having thus described the nature and objects of my invention; what I claim as new,

'. and desire to secure by Letters Patent, is'- divide the sinews or tendons into a fine thread-like material.

2. The herein-described process for manufacturing fiber material from animal tendons .or sinews, which consists in first removing adhering flesh and fatty particles and theskin, then beating and simultaneously turning the sinews around their longitudinal axis to loosen the fiber bundles from each other and from the cement-like albumjnous mass interposed between the same, then cardin the-longitudinally andtransversely arran fiber bundles to'arrange the same paralle to each otherso as to, divide the bundles into fine thread-like material and toremove the albuminous mass therefrom.

In testimony whereof I have signed name 'to this specification in the presence of two subscribing witnesses.
